the bill, about the eye, and on the belly of the other sex. In this 

 species the trachea of the female is simple, but that of the male 

 is terminated by large, swollen, convoluted bronchi. In a male 

 specimen, procured in May, the bronchi ran down right and left, 

 almost straight, for about l-^y^ in., then took a bend forward for 

 a short space, and narrowed, and lastly, bending inwards and 

 upwards, bulged largely, and entered into the lungs. The pro- 

 ventriculus consisted of a large flabby sac, about 3 inches in 

 length, and 1 ^^ in breadth in the broadest part, lessening to ^ in. 

 before it reached the stomach, which was round and muscular, 

 Y^ in. in diameter, and supported by strong circular lateral ten- 

 dons with radiating muscles. Both the stomach and the pro- 

 veutriculus contained a thick greenish-yellow juice j the latter 

 was stocked with remains of fish, and the former with numbers 

 of small gritty stones, some as much as | inch in diameter. In 

 both these were numerous small, thin Ascarides. Intestine 8 

 feet long, and strong, averaging -f- in. in thickness. 



I kept four of this species, and two of the D. hrachyura, alive 

 for some days in my verandah at Amoy, but could not get them 

 to feed. The first few days they used to walk about in a clumsy 

 manner, but afterwards they got weaker and could not manage 

 to rise. Both species had a common habit of stretching the 

 neck and raising the bill upwards, uttering at the same time a 

 loud, hollow-sounded, moaning bellow, as of some animal in pain. 

 The production of this sound seemed to force up oily matter 

 into the mouth, for the birds would go through the movements 

 of swallowing for some time afterwards. Through the day, and 

 often in the night, this miserable moan would be uttered at set 

 intervals. I kept one of this species alive, to see how long he 

 would live without food, and he lived on, week after week, with- 

 out showing any particular signs of weakness, till about the 20th 

 day. He then began to look shaky, but still obstinately refused 

 to eat fish. On the 29th day he died : but his abstinence from 

 food was in reality greater than that extraordinary number of 

 days ; for he had been in the possession of the fishermen who 

 caught him nearly a week before he came to me. When fresh 

 taken in the spring, the birds are particularly fat : but this starved 

 specimen had survived on the gradual absorption of his adipose
